What can Sihver contribute with for the ESS project WP#3 and 11
Nearly 30 years of experiences with nuclear chemistry, nuclear physics,
material science and various applications of these sciences. Long experience of gamma spectroscopy, heavy ion experiments, gamma
spectroscopic analysis of accelerator based fragmentation experiments,
and development of gamma spectroscopic measurements systems. PhD thesis at the department of neutron research, Uppsala University. 20 years of experiences of development, improvements and benchmarking
of deterministic and Monte Carlo particle and heavy ion transport codes. A extremely wide network and collaborations with Japanese scientists at
JAEA, NIRS, University of Tokyo, Tokyo Institute of Technology, Waseda
University., JAXA, RIKEN, etc. A passionate interest for the construction of ESS and all possible experiments
which can be performed at ESS.
